Tue Dec 19 09:03:08 UTC 2023 - Andrea Manzini <andrea.manzini@suse.com>
|
||||
|
||||
- Update to 2.6:
|
||||
* env NO_COLOR support
|
||||
* fix problems with linux/bfd ```init_disassemble_info```
|
||||
* Support ```--exit_on_time```
|
||||
* ```strlcat``` supported in libhfuzz/memorycmp
|
||||
* Some patches for MacOSX, sadly no support for ARM yet
|
||||
* Improvement on Android and FreeBSD targets
|
||||
* added missing ```add missing disassemble_free_target()```
|
||||
|
||||
- Dropped following patches as already included in upstream :
|
||||
* 0001-Always-pass-4-arguments-to-init_disassemble_info-no-.patch
|
||||
* 0002-linux-bfd-use-DIAGNOSTIC_ERROR_SWITCH-define-to-figu.patch
